Title: Purification of nucleic acid using paramagnetic particle and its operation
Inventor: COLLIS MATTHEW P
IPC: C12Q1/6806
Filed: 1999-10-22
Abstract: PROBLEM TO BE SOLVED: To obtain a new composition capable of effectively and efficiently purifying a nucleic acid because the composition can be reversibly connected to a nucleic acid molecule in an acidic solution by making the composition include a paramagnetic particle. SOLUTION: This composition comprises a paramagnetic particle. An iron particle such as magnetic iron oxide, etc., is preferable as the paramagnetic particle. The paramagnetic particle has only to generally have 0.5-20 μ diameter of part of the maximum width. An acidic environment capable of reversibly connecting a nucleic acid molecule to the magnetic particle is preferably obtained by acidifying a solution or an environment comprising the magnetic particle by adding an acidifying agent such as hydrochloric acid, etc. The nucleic acid molecule connected to the paramagnetic particle is eluted in a buffer solution and subjected to an operation such as amplification reaction, etc. The elution is carried out by heating the environment in which the nucleic acid molecule is connected to the paramagnetic particle or increasing the pH of the environment.  A basic solution of potassium hydroxide, etc., may be cited as an agent for assisting the elution of the nucleic acid.

IPC: G11B33/14
Filed: 1994-12-05
Abstract: PURPOSE: To obtain a data recording disk device with an improved breather filter assembly removing both of chemically contaminated material and particulate material. CONSTITUTION: The filter assembly 60 is provided with a housing with an internal passage and a hollow 66 involving chemical and particulate filter element and fixing them. The passage within the filter housing enables fluid communication between a breather opening part 64 and a chemical filter material. A barrier plate 74 is placed also at the hollow of the filter housing adjacent to the side of a chemical filter sheet which is not exposed to air from this passage. The barrier plate prevents the flowing of air through the chemical filter material and turns the direction of air to flow across the surface of the chemical filter sheet 72. After the flow of air by the chemical filter sheet, air turns its direction to pass through the element of a particulate filter 78 to enter the enclose of the disk device.

Title: Heating cooking utensil
Inventor: TAKEI TAMOTSU
IPC: A47J37/06
Filed: 1988-11-29
Abstract: PURPOSE:To make it possible to estimate a remaining heat of a heater at the next starting point of cooking and execute the next cooking at a proper amount of heating by installing a compensation means which compensates the length of cooking time for grill cooking based on power supply time to the heater and the time lapsed. CONSTITUTION:When the time T1 lapsed from the point of end time of the previous grill cooking is detected and the thus detected time does not exceed a specified time (30 minutes), an attempt is made to compute cooking time which is corrected so that it may be shorter than a standard cooking time T0. Based on this cooking time, the next grill cooking is designed to be executed. Therefore, the remaining heat of a heater 4 is capable of preventing excessive heating of food previously. Furthermore, consideration is not limited to the time T1 lapsed, but also this construction is designed to compensate cooking time in consideration for a power supply time T2 to the heater 4 in the previous grill cooking when the time lapsed T1 is below a specified value. Therefore, when a slight amount of heat remains in the heater 4, as power is supplied to the heater 4 only for a short time in the previous grill cooking, it is possible to prevent the setting of excessively shorter cooking time previously.

Abstract: PURPOSE:To improve migration-resistant properties of a fine aluminum wiring by a method wherein the wiring film of an integrated circuit has a multilayered structure composed of aluminum layers and other metallic, layers of 1-20 nm thickness which are alternately built up. CONSTITUTION:A wiring film 1 is composed of aluminum layers 2A-2E and other metal (for instance titanium) layers 3A-3D which are alternately built up and is usually formed on an insulating film (for instance SiO2 film) 5 on a semiconductor (for instance silicon) substrate 4.

If the thickness is larger than 20 nm, a thermal stress is induced by the difference in thermal expansion coefficient between the metallic layer and the aluminum layer which causes stress migration. On the other hand, a metallic layer whose thickness is less than 1 nm is difficult to be formed with a high accuracy by a sputtering method or a vacuum evaporation method.
